 Water Chillers are generally divided into the following categories: screw chillers, centrifugal chillers, water ring heat pump units, plate and tube evaporative condensing screw chillers, thermal storage air conditioners, etc. Screw chiller and centrifugal chiller are equipment that we often encounter. Below,  Oumal Refrigeration  will take you to understand the difference between centrifugal chiller and screw chiller? What is a  screw chiller ? The compressor adopts a screw type, hence the name screw chiller. The refrigerant coming out of the evaporator of the unit is a gas; after adiabatic compression by the compressor, it becomes a high-temperature and high-pressure state. The compressed gas refrigerant is isobarically cooled and condensed in the condenser. After condensation, it changes into liquid refrigerant, and then expands to low pressure through the throttle valve and becomes a gas-liquid mixture. The liquid refrigerant under low temperature and low pressure absorbs the heat

  A   screw chiller , also known as a screw compressor chiller, is a type of water chiller utilized for cooling applications in various industries, including injection molding. The semi-hermetic screw compressor is the core components of a screw chiller.  It operates based on the principle of a rotary screw compressor, which is a positive displacement compressor. The screw compressor consists of two interlocking helical rotors that compress the refrigerant gas to raise its pressure and temperature. According to different heat dissipation methods, screw chillers are divided into  air-cooled screw chillers  and water-cooled screw chillers. Under the same cooling capacity requirement, the purchase cost of water-cooled screw chillers is lower than that of air-cooled screw chillers. As far as chiller installation is concerned, air-cooled screw chillers are easier to install. Here are some key features of a screw chiller: Cooling capacity: Screw chillers are available in a wide range of cool
